FastStone Capture vs Snagit

Such as saving images in BMP, GIF, JPEG, PCX, PNG, TGA, TIFF and PDF formats as well as the screen recorder saving videos in the WMV (Windows Media Video) format.

This responsive, lightweight screenshot will probably be your favorite if you really run it through the test, A scrolling window capture that works, integrated image joining, scanner support, good magnified preview when setting boundaries, support for video capture and editing. Free upgrades for paid version with option for portable. Closest alternatives to feature set are Snagit and Shared, but this one feels much snappier with just the right features for the majority of people. Try it, you will not regret.

You can assign hotkeys for everything. Current setup is:
F5 - Fixed rectangle capture
F6 - Custom (drag a square) rectangle capture
F7 - Video capture 30fps
F8 - Fullscreen capture
F9 - Scroll fullscreen capture
F10 - Summon FS to appear if hidden.

When capture hotkey pressed - FSC will pause all functions going on in your screen so you can capture website dropdown menu for example, which would disappear otherwise when you leave the website window to press the capture tool.

Always available via hotkey, doesn't interfere with any programs or operations.

Allows you to adjust the capture, add captions and symbols (arrows, boxes etc).

Simple to choose between full-screen, window or a selected area.

The editor allows you to quickly and easily​ mark and annotate the screen capture.

Google drive, Twitter, Facebook, email etc.

Allows you to arrange the screen as you want it captured. Things like opening a popup menu, to have it part of the capture.

Just about any text on the screen can be editable text. I say "just about" because it's like OCR software in that unusual and extra fancy fonts or text against a low contrast background may be a challenge. But overall it works in most situations.
